Find & Remove Duplicate Songs by Sound — Not Just File Names
Audio Comparer finds duplicate songs by analyzing their actual audio — not file names, tags, or sizes. Even if your tracks are renamed, converted to another format, or missing metadata, our software still recognizes them as duplicates.
Clean up your music library in minutes and free up valuable hard drive space. Works with MP3, FLAC, WAV, AAC, WMA, OGG, APE, and more.

- Processes each song in 1–2 seconds — fast scanning, instant results
- Groups similar tracks in a visual tree for easy review

Powered by Audio Fingerprinting Technology
Unlike basic duplicate finders that rely on file names or tags, Audio Comparer actually "listens" to your music — just like a human ear. Using advanced audio fingerprinting (the same tech behind our award-winning Image Comparer and Video Comparer), it identifies duplicates based on actual sound.
Supports MP3, WMA, FLAC, WAV, AAC, OGG, APE, WavPack, AIFF, and more — no matter the codec or bitrate.
Perfect For:
- 🎵 Music lovers with messy libraries and hidden duplicates
- 🎙️ Podcasters & DJs who need clean, reliable audio files
- 📻 Broadcasters avoiding accidental repeats
- 💾 Anyone running out of disk space due to redundant tracks
- 🎧 iTunes users tired of seeing the same song twice

What Users Say
"Just want to let you know how good Audio Comparer is! Its helps me to deal with my huge collection of audio files, while I am doing purely nothing. When I first tried to use it, it turned out I`ve got hundreds of audio duplicates on my computer and in my iTunes library as well... So, I had to bring it to order but it would take years to organize it... Audio Comparer did this within several minutes!!! That`s fantastic! Thanks to the developers for the posh program!"
